Iridium (Ir) crystallizes in a face centered cubic lattice with an edge length of 383.9 pm. What is Iridium's density? (a) 5.641 g/cm^3 (b) 11.28 g/cm^3 A) A cube of osmium metal 1.500 cm on a side has a mass of 76.31 g ...
Brain electrodes have been manufactured with a variety of different materials, including tungsten, platinum, iridium oxide, titanium nitride, poly(ethylenedioxythiophene) (PEDOT). The quality of the recording electrodes depends on their impedance at 1 kHz, in vivo usually ranging between 50 kΩ...
